Abstract： T he outstanding features of high pressure water jet comminution lie in its high comminuting efficiency‚low energy consumption‚tensile crushing principle‚good cleavage ability‚ thus the original crystalline form and the surface glossiness of the ground materials can be well preserved．T he comprehensive situation of the study of water jet comminution technology was reviewed．T he experimental investigation of grinding mill scale‚ which is a material processing step for permanent magnetic fer rite production‚was introduced．T he preparation of the water coal slurry and pearlite－mica powder by water jet were also in troduced．
